Passing parameters in URL

Hi,

I'm having a lot of trouble with passing get parameters in through the url using JSF.

I have links generated in a dataTable:

<h:outputLink value="showObject.faces">

<h:outputText value="#{object.description}"/>

<f:param name="objid" value="#{object.id}"/>

</h:outputLink>

This generates a link to "showObject.faces?objid=3" which looks fine.

But when I click on it I get the exception:

exception

javax.servlet.ServletException: viewId:/showObject.faces - View /showObject.faces could not be restored.

root cause

javax.faces.application.ViewExpiredException: viewId:/showObject.faces - View /showObject.faces could not be restored.

Anyone has any idea what's causing this?

The page showObject.faces shows up nicely if no parameters are passed.

Br,

/Richard
